LANTERN.

SPECIFICATION forming part of Letters Patent No. 275,509, dated April 10, 1883.

Application filed March 9, 1883. No model.) Patented in Canada March 6, .883, No. 16,442.

tion, reference being bad to the accompanying drawings, forming part of this specification,

- and to the figures and letters of reference marked thereon.

Myinvention relates to improvements in that class of lanterns known to the trade as tubular lanterns; and it consists in certain novelties of construction, which I will first describe, and then point out particularly in the claims at the end of this specification.

In the accompanying drawings, Figure 1 represents a longitudinal vertical section of a lantern embodying. my improvements. Figs. 2, 3, and 4 represent a series of modifications of the locking device. Fig. 5 represents a modification of the mode of connecting the tubes.

The letter A designates the base of the lan tern, adapted to contain the oil, B the wick,

O the wick-raising device, D the burner-cap, E the perforated plate rigidly attached to the cap D and adapted to support the glass globe, and F the glass globe, all of said parts being of the usual or any preferred construction.

Extending up .from the base A, on opposite sides of the lamp, are two tubes, G G, preferably curved to conform to the general outline of the globe, except from the points g to h, where they are made straight and vertical. The upper removable portion of the lantern, H, is provided with downwardly-extending tubular portions I I, which are adapted to inclose and slide upon the main tubes G G, as shown. The removable upper portion is further provided with a central tubular part, J, which carries a shield or deflector, K, and spring-jaws L L for grasping and holding the upper end of the globe, as shown.

Arranged within the removable upper portion or top is a spring-lockin g contrivance, which, as shown in Fig. 1, may consist of a single piece of springy metal wire, M, having a horizontal portion, m, extending through the horizontal tubular portion of the top, and

formed with eyes a on the outside of the top, and thence passing downward through the vertical tubular portions I I, and formed into bent ends 00, which normally project through perforations p p in the tubes I I near their lower ends.

Riveted, soldered, or otherwise secured to or formed with the horizontal portion of the spring wire is a short stem, q, having upon its projecting end a pressing-button or thumbpiece, 1'. By pressing upon this button or thumb-piece r the horizontal portion of the wire spring will be bent down and the downwardly-extending parts 8 s will be thereby sprung outward, so as to retract the locking ends 0 0. In applying the top the locking ends of the spring are retracted by pressing the thumb-piece, as described, and the tubes I I are fitted upon the tubes G G and pressed down until the perforationspp in the tubes I I come opposite to corresponding perforations, t t, in the tubes G G, whereupon the locking ends of the spring will be automatically projected through the perforations in both sets of tubes, thus securely lockin g the parts together. When the thumb-piece is again depressed so as to disengage the locking ends ofthe spring the top may he slipped oft, as will be readily understood.

In order that the top may be raised without being taken entirely 05 for the purpose of removing or adjusting the globe or to gain access to the burner, I provide the lower tubes, G G, with another set of perforations, u a, with which the locking ends of the spring are adapted to engage when the top is nearly oft, so as to lock the top in that position.

The single spring, it will be observed, serves to lock or unlock both sets of tubes simultaneously, and constitutes a very cheap, simple, and effective contrivance. Various modifications of its form may be suggested. For instance, instead of forming it into eyes it at the extremity of its horizontal portion, as shown spring, the central button or thumb-piece being in such case dispensed with. The modification represented in Fig. et shows the locking-spring formed with a bend, 10, at the middle, which serves as the thumb-piece for operating it. lhe spring; may consist of ordinary round wire of the requisite degree of elasticity, or it may be made flat or of such other shape as may suit the fancyof the construoter. To apply the spring to the tubular top portion the latter may be made in halves provided with suitable slots accommodating the projecting portions, and the halves may be secured by soldering, creasing, or in any other manner known to metal workers.

As shown in Fig. 5, the tubes of the top may lit within the lower tubes instead of fitting over them, the efiect in both cases being substantially the same.

Stops z .2 may be formed on the tubes G G to limit the downward movement of the tubes I I.

Havingthus described my invention, I claim as new- 1. In a tubular lantern, the combination, with the removable top having the depending tubes,ofasingleinclosed springhavinglocking ends, one for each depending tube.

2. In alantermthe combination of the base, the upwardly-extending tubes, the removable top having the depending tubes, the single spring having its opposite locking ends arranged in the depending tubes of the top and adapted to engage with the corresponding lateral perforations in the tubes, substantially as described.

3. In a lantern, the combination, with the removable top, of the spring having the horizontal portion,thedownwardly-extendinglocking ends, and provided with the operating button or thumb-piece, substantially as described.

4. In a lantern, the combination, with the removable top, of the inclosed spring having the horizontal portion, the projecting eyes or loops, and the depending locking ends, sub stantially as described.

5. In the herein-described lantern, the base, the upwardly-extending tubes conforming to the contour of the globe except attheir upper ends, here the) are made straight, in combination with the removable top having the depending tubes fitting the lower tubes, and the inclosed single spring having the locking ends for locking the tubes together, both such ends being simultaneously operated by bending the horizontal portion of the spring, substantially as described.
